How do the amounts compare with the Daily Value and the upper limit?

The FDA Daily Value for vitamin K is 120 mcg (adults and children 4 and older). The median product gives 67% of it per serving; the 90th percentile 150%.

The upper limit is for total intake from food, water and supplements unless stated, and does not apply under medical supervision. A label amount is what the maker printed. This is data, not advice: the NIH ODS fact sheets explain what each nutrient does.

Sources: 21 CFR 101.9(c)(8)(iv) (Daily Values); Institute of Medicine, DRI summary tables (2011) (upper limits); on reading them, the FDA's Daily Value page.

Which forms of vitamin K do labels name?

Vitamin K1 (phylloquinone) is the form named most often: 1,879 of the 4,722 vitamin K products (40%), ahead of vitamin K2 as MK-7 (1,376, 29%) and vitamin K2 as MK-4 (277, 6%). A product naming two forms counts in both; the table below gives every form.

Which products list the most vitamin K?

On-market products, per serving, with a plausible amount: the rule leaves out likely entry slips, such as an amount far beyond every other label with no %DV or strength on the label to back it (each product page still shows its own amount, marked).

Have the amounts changed over the years?

Products whose current label entered DSLD in 2011 list a median of 77.8 mcg; those entered in 2025, 81 mcg.
